What Happened

Railroads tied distant markets together, changed travel time, accelerated settlement, and reshaped work across the continent. The achievement also depended on immigrant labor, especially Chinese railroad workers, whose contributions are essential to the story.

Why It Matters

The railroad made the United States feel smaller, faster, and more economically connected.

Worth Knowing

A cross-country journey that once took months could be made by rail in about a week.
